The 10 warmest places within 15 hours of Copenhagen

Ranked on warmth in June alone, among well-known places (a Wikivoyage travel guide and at least 40,000 Wikipedia readers a year), one per area and at most three per country. The carbon is shown, not used to choose: the list further down is the other question, how much warmth each extra kilogram buys.

The low-carbon trade-off

The warmest place you can reach from Copenhagen in June within 15 hours is Luxor, 35.9 °C, costing 868 kg CO₂e return. The lowest-carbon option is Karlshamn at 4.5 kg — 193× less carbon, for 20.0 degrees less warmth.

Every destination here is on the efficiency frontier: nowhere else this site covers is both warmer in June and lower in carbon. Anything a better option beats outright has been left out.

Carbon against warmth, June, departing Copenhagen. Journeys of up to 15 hours each way.

What the 15-hour limit costs: at this budget Venice can only be reached by air — 286 kg CO₂e, in 5h. Allow up to 24 hours and the train does the same journey for 33.6 kg in 18h 24m — 9× less carbon for 13h 24m more travelling.

Where the curve breaks

The frontier is gentle until it isn't. Going from Ludwigshafen am Rhein (21.9 kg, 20.0 °C) to Komárno (241 kg, 20.9 °C) buys 0.9 °C more warmth for an extra 219 kg — 244 kg of CO₂e per degree. That single step is the most expensive warmth on the whole curve.

The same month, asked differently

June answers differently depending on what you are after, and the lists genuinely diverge: the brightest places are not the hottest, and in summer the useful question stops being where is warm at all.
